Specification of Letters Patent.

Patented June 4, 1907.

Application filed November 12,1906. Serial No. 343,002.

To all, whom it may concern.-

Be it known that I, h lARTIN Fannnns, a citizen of the United States, residing at Diller, in the county of Jefi'erson and State of Nebraska, have invented certain new and useful Improvements in Incubators, of which the following is a specification.

M invention re ates to improvements in and has particular reference to the heat regulating device for such an incubator, the object of the invention, being to provide a sim lified and durable construction which wil operate with precision and cause the incubator to be kept at the same oven temperature.

Another object of the invention, is 'to provide adjustable connections for the diiferent,

parts so that such parts will always be erlv balanced and may be readily regu to suit different conditions.

With these and other ob ects in view, my

ropated invention consists of an .incubator provided with a suitable thermostat, a lamp of any ordinary type for maintaining the proper heat in the incubator, adjustable lever connections adapted to be actuated by the thermostat to control the lamp, and in still further providing means for ad uSting the balance of the lever connections.

My invention further consists of an incubator embodying certain other novel features of construction, combination and arrangement of parts substantially as herein set forth. i D

Figure 1, is a werspective view of an incubator of the or inary type having myimrovements applied thereto. Fig. 2, 1s a liroken elevation to show the manner in which the thermostat and operating lever are connected, the top of the incubator, to which the thermostat and lever are secured, being shown in section. Fi 3, is a detail view of the lampcontrolling device, the end of the operating lever and the connection therebetween.

My invention does not relate to any particular style or type of incubator, and may be as rcadilv used upon one sort as another, as it an attachment for controllin the heating medium for the-incubator, an such improvements will now be described 111 detail: i

In the drawings: the numeral 1 designates an ordinary incubator upon the top of which is secured a plate 2, bearing a pair of parall el standards 3,which by means of the pivot pin 4, su port the lever 5, therebetween. S acing b ocks 5, are secured to the sides of the lever to kee it properly spaced between the bearings. he incubator is provided with the usuallamp 6, having a thumb nut 7, for turning thewick of. the lamp, up or down, to regulate the heat thereof. Pivoted to. the forward or long arm of the lever, is a rod 8, which overhangs the edge of the top, extends downward and is in turn pivotall y connected to a small lever 9. This small lever 9, is in the shape of an arc and has end oppositethe one to whic connected, a clamping member or bar 10, the other end of which is adjustably securedto the lever 9, by the clamping screw 11. it will be seen by referring to the drawings, (see especially Fig. 3) that the thumb nut which regulates the lamp, is clamped to the the wick is given a corresponding movement. The end of the lever 9, is also provided with a series of openings 12, to receive the lower end 01': the rod 8, so that the leverage on the wick regulator may be chan ed as desired.

VVitlnn the incubator an preferably'secured to the lower or under side of the top thereof at a point in rear of the pivotal support of the operating lever 5., is an archshaped frame 13. Secured to the arched ortion of the frame by means of the nut 14, 1s a thermostat, comprising the two inde pendent series of air ce ls 15, arranged upon a common axis 16. To the upper end of the thermostat is pivoted a rod 17,which extends up through the top of the incubator, and'enages one of the series of openin 18, in the plate 19, said plate being pivote to the lever at one end as 20, the other end of the plate being slotted to receive the bolt 21, and a set screw22, on said bolt servesto hold the plate in the adjusted osition. Beneath the series of openings in t e plate, the lever is rovided with a recess 23, (shown in dotte lines in Fig. 2) interfere with the adjustment of the plate. In the rear end of the operating lever 5, is mounted a threaded shank '24, which supports a rotatable weight 25, said weight being threaded in or out on the shank to adjust the balance of the lever. A damper 25, may also be suspended from the forward end of the operating lever to act in conjunction with the lamp.

The operation of my device w ll be readily understood. As the air'infiie incub ator betpivoted to the the rod-8,-i s

The balance of the operating'lever' .may be adjusted by shifting the weight -'on comeSh'eated, the thermostat expands, therebyforcing their-ear end of the lever upward caus' the same to turn thewick of the lamp down 37 means of the rod and clampin The device is capable o the end thereof; the position of the lever with respect to the thermostat may be varied by changing the angle of the slotted plate thereon; the leverage and movement of the wick-operating means may be altered by shifting the connecting rod 8, in the series of openingsin the clamping lever; and the c amping lever'is adjustable to receive wick opei-atihg'ineans of various sizes and shapes.

' From the above description taken in conneiition'with the drawin s it will'be evident ent air cells adjustably secured together and arranged-in the incubator, of an operating that'I have accomplishe all the objects herein set forth and have produced a practical and efficient heat regulating means for incuhaters. v i
